Overview
SMBJ60CA-E3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 96.8 V maximum clamping voltage (VC) at 6.2 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ60CA-E3/52 datasheet, SMBJ60CA-E3/52 pinout, SMBJ60CA-E3/52 application, or SMBJ60CA-E3/52 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.45), MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both directions, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the 20 °C/W junction-to-lead thermal resistance supports reliable surge energy dissipation under repetitive transient conditions.
The device complies with ANSI/IEEE C62.35 for transient suppressor definitions and meets UL 497B recognition (QVGQ2) for telecom and industrial protector classification. It is rated for -55 °C to +150 °C operating junction temperature and derates linearly above 25 °C ambient per Figure 2 in the datasheet.

Applications
| Industrial Motor Drives | Telecom Power Interfaces |
|---|---|
|
Use Scenario: Protection of gate drivers and bus voltage sense inputs against switching transients from IGBTs and contactor bounce. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across DC bus or isolated gate drive transformer secondary. Use Value: Limits transient overshoot to ≤97 V, preventing gate oxide rupture in 100 V MOSFETs and false triggering of overvoltage comparators. |
Use Scenario: Surge suppression on -48 V telecom power feeds exposed to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Primary-level TVS connected line-to-line and line-to-ground on power entry board. Use Value: Withstands 600 W pulses without degradation, maintaining <1 µA leakage to avoid load regulation drift in precision DC-DC converters. |
| Automotive Body Control Modules | Industrial Sensor Signal Conditioning |
|
Use Scenario: Protecting LIN bus transceivers and microcontroller I/O pins from load dump and ISO 7637-2 pulse 5a transients. IC Role / Device Role / Timing Role: Bidirectional clamp between LIN data line and ground, placed adjacent to connector. Use Value: Fast response (<1 ns) and low VC ensure transceiver remains within absolute maximum ratings during 100 V/50 ms load dump events. |
Use Scenario: Shielding 4–20 mA current loop receivers and analog front-end op-amps from ESD and inductive kickback. IC Role / Device Role / Timing Role: Low-capacitance (≈100 pF at 0 V) TVS placed directly at connector entry before signal conditioning stage. Use Value: Clamps 8 kV HBM ESD strikes to <100 V while adding negligible capacitance that would distort 10 kHz sensor bandwidth. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA-M3/52 | Halogen-free, RoHS-compliant variant; identical electrical specs and SMB package. | No difference in circuit performance or layout; selected only where halogen-free compliance is mandated. | Choose when environmental compliance requires halogen-free materials without altering design or test validation. |
| SAC60CA | Same VWM/VC but in SMC (DO-214AB) package; 20% larger footprint and higher RθJA (75 °C/W vs. 100 °C/W). | Lower power density; less suitable for space-constrained 48 V DC/DC modules with tight thermal budgets. | Select only if existing SMC footprint reuse is prioritized over board area efficiency and thermal performance. |
Compared with SMBJ60CA-E3/52, the M3 variant offers identical protection performance with halogen-free construction, while SAC60CA trades compact SMB size and superior thermal resistance for legacy SMC compatibility - making SMBJ60CA-E3/52 optimal for new designs demanding high power density and MSL Level 1 process support.

FAQ
What is the clamping voltage of SMBJ60CA-E3/52 under a 10/1000 µs surge?
The SMBJ60CA-E3/52 has a maximum clamping voltage (VC) of 96.8 V at 6.2 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per Figure 1 and Table on page 2 of Vishay document 88392 and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The SMBJ60CA-E3/52 maintains this clamping performance across its full operating temperature range.
Is SMBJ60CA-E3/52 suitable for automotive applications?
SMBJ60CA-E3/52 is commercial-grade; however, the functionally identical SMBJ60CAHE3_B/H variant is AEC-Q101 qualified for automotive use. The SMBJ60CA-E3/52 itself meets UL 497B recognition and operates from -55 °C to +150 °C, but lacks formal automotive qualification testing. For body electronics or infotainment systems requiring AEC-Q101, specify the HE3 suffix version instead of SMBJ60CA-E3/52.
What is the thermal resistance of SMBJ60CA-E3/52, and how does it affect layout?
The SMBJ60CA-E3/52 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, indicating efficient heat conduction from die to PCB copper via soldered leads. To realize this value, Vishay specifies mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Deviating from this pad layout increases effective thermal resistance and reduces safe surge repetition rate for the SMBJ60CA-E3/52.
Does SMBJ60CA-E3/52 have polarity markings, and how is it installed?
No - SMBJ60CA-E3/52 is a bidirectional TVS diode and carries no cathode band or polarity marking. It is symmetrically constructed and may be installed in either orientation on the PCB. Unlike unidirectional variants (e.g., SMBJ60A), the SMBJ60CA-E3/52 functions identically regardless of terminal connection direction, simplifying assembly and eliminating orientation errors during automated placement of SMBJ60CA-E3/52.
What is the maximum leakage current of SMBJ60CA-E3/52 at its rated standoff voltage?
At its 60 V standoff voltage (VWM), the SMBJ60CA-E3/52 exhibits a maximum reverse leakage current (ID) of 1.0 µA at 25 °C, per the Electrical Characteristics table on page 2 of Vishay document 88392. This ultra-low leakage ensures minimal impact on high-impedance sensor bias networks or battery-powered circuits where quiescent current must remain below 2 µA - a key advantage of the SMBJ60CA-E3/52 over higher-leakage alternatives.
